@Rileywd This error pops up when a node in your workflow crashes, and it’s usually because of bad data, missing credentials, or an API saying “nope.” For example, I was using the HTTP Request node to pull data from a REST API, and it failed because the JSON payload I sent had a typo in a field name. Another time, my Google Sheets node failed because the OAuth token expired. I’ve also hit API rate limits when hitting a service like Twitter too fast.
To fix it, first check the node’s error message in the execution log, it usually points to the issue, like “Invalid JSON” or “Missing credentials.” For data issues, Just copy the input JSON and paste it into a JSON validator like jsonlint.com to spot errors. If it’s credentials, re-authenticate in the Credentials section, making sure the API key or OAuth token is fresh. For rate limits, add a Wait node with a 1 sec delay or lower the batch size in the HTTP Request node to, say, 10 items per call. Testing the node in isolation helps me catch the problem without running the whole workflow.
